Engine ID Number?

Question

I just recently replaced the engine in my f-150, and I have a sneeky suspicion that the mechanic rebuilt my motor and charged me for a new one. He said my motor was bad, and that I need a new one, so I paid for the new one plus the additional charges because the core was bad. Is there any way I can tell by the engine ID number if the new motor is actually the old motor, but just rebuilt? Thx in advance.

1998 F-150 4.2L

Answer 1

Ford engine identification

You neglected to list the year, and ID # of your engine, so this is the best I could do.

Ask the dealer to confirm the ID numbers of the new/rebuilt engine from your paperwork for warranty purposes. Then ask for them for the ID numbers of the old engine and the disposition of the old engine. Compare what you have. If they said they couldn't turn your old engine in as a core unit because it was so bad, ask for proof that they scrapped the old engine or ask to see it. If you just had it done they might have the engine still there. I had a Ford dealer put an engine in my car and it took about six weeks for the replacement to come in. If the engine ran out of oil and it started banging and or seized up and stopped, I would think that it would have broken something internally and maybe wasn't any good.
